PHILIP FBAZIER AND RAYMOND E. ACKLEY, CHICAGO, ILLINOIS, ASSIGNORS TO B. R. DONNELLEY 8c SONS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

BOOKBINDING MACHINE.

Application filed November 12, 1923. Serial No. 674,243.

To aZZ whom it may concern: Be it known that we, PHILIP FRAZIER and RAYMOND E. AoKLnY, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Bookbinding Machines, of which the following is a specification.

This invention relates to book binding ma- 1U chines and particularly to means for applying pressure to the covers of the books so as to bring them intimately into contact with the bodies of the books.

The invention is fully described in the following specification and shown in the accompanying drawings in which:

Figure 1 is a partial top plan view of a book binding machine embodying the invention;

Fig. 2 is a partial side elevation of the same;

Fig. 3 is a vertical section on the line 3-3 of Fig. 1; v

Fig. 4 is an enlarged partial longitudinal section on the line 4 of Fig. 3; and

Fig. 5 is a section on the line 5 of Fig. 4.

The embodiment shown is adapted to be applied to a book binding and covering machine of the general type shown in the patent to Bredenberg, No. 1,073,324, granted September 16, 1913, in which the machine has a main frame 10 about which is supported by suitable means, not shown, two parallel channels 11 and 12 (Fig. 3) having facing guideways in which rollers 13 and 14 may pass. These are journaled on suitablepins which serve to connect the links 15, 16 and 17 of the continuous chains.

' These links carry clamping plates 18 which are guided at their ends by pins 19 and are adapted to receive and hold the books A, A, A etc., as shown in these various positions in Fig. 2. These books are held in the clamps by means of the springs 20. The details of this loose book gripping mechanism is fully shown and described in the patent to Bredenberg above referred to.

Before the books have reached the position shown in Fig. 2, the loose leaves of the unbound books A after being securely gripped by the plate 18, have been trimmed on the lower surface so that the bottom edges of the pages of the book A present a smooth edge like the unbound edge of a tablet, and this lower edge which is parallel to the direction of the motion of the chain has been coated with glue preparatory to receiving the flexible cover of paper or similar material. A

piece of gauze commonly known as a super (not shown) is applied over the glue-d portion to assist in holding the finished book together.

A flexible belt 21 passes around pulleys 22 and 23, the former being keyed to the shaft 24 which has a sprocket 25 which is driven by a sprocket 26 which is keyed to the shaft 27, the latter being driven by means of bevel gears 28 and 29 on the shaft 30 which is operably connected to the mechanism, not shown, for driving the chain consisting of the links 15, 16 etc.

The flexible belt 21 consists of leather, common rubber belting or the like, has a series of transverse strips 31 or the like secured thereto. These are curved inwardly for a purpose which will later appear. This belt travels below the line of books A, A etc., and is so geared as to travel at the same rate of speed and in the same direction.

A series of rollers 32 (Figs. 4 and 5) are journaled upon pins 33 the ends 34 of which being flattened are slidable up and down in grooves 35 in the guide member 36. This member is adjustable vertically by means of an adjusting screw 37 at each end. These screws are turned by means of heads 38 and are screwed into castings 39 which have lugs 39 by which they are secured to standards 40 and 40 which are carried by the main frame 10. Springs 41 are placed beneath the flattened ends 34 of the shafts 33 so as to normally hold these ends up against the strips 42 which are secured to the member 36 by means of screws 43.

A series of parallel chains 44 are driven by suitable sprockets 4-5 on the shaft 24 and travelaround sprockets 46 on the shaft 47 which is journaled in the brackets 48. These chains carry a series of lugs 49 which are spaced at regular intervals and so timed that'they come even with the rear ends of the books A, A etc., as shown in Fig. 2.

The covers B are fed to the chains 44 by means, not shown, so that a cover will be caught by each of the lugs 49 and will be carried along a short distance beneath one of the books in. the position A of Fig. 2. As the book and wrapper advance to the position A, B, the cover will be carried up into contact with the glued lower edge of the book A and the two will progress to the position A, B where the cover is placed firmly against the book by means of the pressure belt 21 which is forced upwardly by means of the spring pressed rollers 32 as shown in Fig. 4.

While the book is in the position A two parallel shoes (Figs. 1 and 3) are moved over the tops of the metal strips 31 and be neath the cover B so as to force the front and back covers firmly against the side of the book adjacent thev glued edge. This is accomplished by securing lugs 51 to the lower surface of these plates through which pass adjusting screws 52 which screw into the lugs 53. These lugs are journaled upon pins 5st which are eccentrically carried by the plates 55. These plates are carried by shafts 56 which have bevel gears 57 meshing with bevel gears 58 on the shaft 59. This shaft is driven by means of a spur gear 60 which meshes with a gear 61 on the shaft 27. As the plates 55 revolve in opposite directions they cause the shoes 50 to be forced inwardly parallel to themselves fore, ing the covers against the sides of the book and traveling for some distance in the same direction that the book is moving and at substantially the same speed. Adjustment of the shoe 50 to accommodate books of varying thickness is accomplished by means of the screws 52. A spring metal plate 62 is held a short distance above each of the shoes 50 so as to act as a shieldto support the outer ends of the covers B as they pass along over the shoes 50. I

This arrangement has the greatadvantage of moving the book A and coverB through the machine together and of applying pressure to the back of the cover by means of the traveling plates 31 which are also moving in the same direction and at the same speed as the book and cover. This insures that the cover will fall at the proper place upon the book and that the two will be pressed firmly together.

This method of pressing the cover on the book causes the glue to pass through the gauze or super to spread more uniformly over the inner contacting surface of the cover, thereby insuring a more uniform and permanent binding, and consequently a much better and stronger book than has heretofore been possible with the machines commonly used for pressing on the cove-rs.

While we have shown and described certain embodiments of our invention, it is to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement may be made without departing from the spirit and'scope of the invention as disclosed in the appended claims, in which it is our intention to claim all novelty inherent in our inven tion as broadly as possible in View of the prior art.
